How to shoot 16:9 and Extracting 4:3
 

I am trying to figure out how to shoot 16:9 and 4:3 with the P2cards for a client so they have both options. How can I extract 4:3 out without sqeezing the image.

You can either crop the 16:9 to 4:3 or letterbox it.

But are you looking for an in-camera solution?

4:3 is SD only anyway....
Shoot 16:9 HD with the 4:3 guides and
then you can have 16:9 HD, 16:9 SD and 4:3 SD

There's an option to show 4:3 safety lines on the LCD and viewfinder. I think it's in Display options.
